Readme
This project is a fork of https://github.com/jm-david/emoji-mart-vue with many performance fixes, tests and structural code changes. See the changelog for details.
The original component was very slow to show/destroy, around 2 seconds to show and even a bit longer to destroy, so it was unusable in a popup.
This was the reason to fork and change it, the demo is here, use the "Show / hide the picker" button to see create/destroy performance
The original project has been forked from emoji-mart which was written for React.
Demo app
Live demo app: https://serebrov.github.io/emoji-mart-vue/ Demo application code is under the ./docs folder.
Installation
Install from npm: npm install --save emoji-mart-vue-fast.
It is also possible to install directly from github (could be useful for forks): npm install --save serebrov/emoji-mart-vue#5.4.9.
Here is the list of releases.
Vue 3 Support
Component works with Vue 3, here is a simple demo app.
Live demo: https://serebrov.github.io/emoji-mart-vue3-demo/.

Emoji Mart doesn’t automatically insert anything into a text input, nor does it show or hide itself. It simply returns an emoji object. It’s up to the developer to mount/unmount (it’s fast!) and position the picker. You can use the returned object as props for the EmojiMart.Emoji component. You could also use emoji.colons to insert text into a textarea or emoji.native to use the emoji.
Components
Picker
import data from 'emoji-mart-vue-fast/data/all.json'
import { Picker, EmojiIndex } from 'emoji-mart-vue-fast'
let emojiIndex = new EmojiIndex(data)Import CSS with default styles:
import 'emoji-mart-vue-fast/css/emoji-mart.css'Note: to have a custom look for the picker, either use own css file without including the standard one or add custom styles on top of standard.
Note: CSS also includes background images for image-based emoji sets (apple, google, twitter, facebook). The images are loaded from the unpkg.com. To use self-hosted emojis sheet, override CSS like this:
/* load twitter sheet from own server */
.emoji-mart-body .emoji-type-image.emoji-set-twitter {
background-image: url(/img/twitter-5.0.1-sheets-256-64.png);
}<picker :data="emojiIndex" set="twitter" />
<picker :data="emojiIndex" @select="addEmoji" />
<picker :data="emojiIndex" title="Pick your emoji…" emoji="point_up" />
<picker :data="emojiIndex" :style="{ position: 'absolute', bottom: '20px', right: '20px' }" />
<picker :data="emojiIndex"
:i18n="{ search: 'Recherche', categories: { search: 'Résultats de recherche', recent: 'Récents' } }"

Picker Usage And Native Emoji vs Images
The select event described above can be handled to insert the emoji into the text area or use it in any other way.
This component does not enforce the usage pattern and it's up to the application how to handle the emoji after it was selected.
For example:
<picker :data="emojiIndex" @select="this.selectEmoji" />
...
selectEmoji(emoji) {
// Assuming the `textContainer` method that returns the
// text container component with `enterText` method.
const textContainer = this.textContainer()
// Enter the native emoji
textContainer.enterText(emoji.native)
}The above will use emoji.native to insert native emoji into the input.
This is the simplest way to use the component and it works relatively well in latest versions of native browsers and latest operating systems. Here, we rely on native unicode emojis support, which, theoretically, should be handled just like any other unicode characters.
In practice, the support for native unicode emoji is still not perfect: unicode emoji characters are part of the font and the font needs to be colorful. But there is no yet a single standard for color fonts implemented by browsers, so the browser leaves emoji rendering to the operating system.
This way, how the emoji will look depends on the operating system and native unicode emoji will look different on different platforms. Also older operating system versions don't not support all the emojis that are currently in the unicode standard, so it may be necessary to limit emojis to some smaller subset.
More consistent solution is also more complex: we can use emoji.colons to insert emoji in the "colons" syntax (such as :smile:) and use regular expressions to find and render the colons emoji as images.
In this case the application can keep text emoji representation and replace before rendering wherever needed (browser, mobile app, email).
The good part here is that we get rid of most of the problems, related to unicode, we work with plain text. For example, in the database the application could have a text like "Hello :smile:" which will be turned into emoji with javascript and even if we leave it as a text (due to the bug or lack of javascript support), it will still make sense.
The bad part is that conflicts are possible - if someone enters the :smile: text, it will turn into emoji.
The emoji.getPosition() might be useful in this case to get the emoji position on the emoji sprite sheet.
The replacement can be done approximately like this:
const COLONS_REGEX = new RegExp(
'([^:]+)?(:[a-zA-Z0-9-_+]+:(:skin-tone-[2-6]:)?)',
'g'
)
/**
* Replace emojis insdie the `text` with `<span>`s.
*/
export function wrapEmoji(text: string): string {
return text.replace(COLONS_REGEX, function(match, p1, p2) {
const before = p1 || ''
// We add "data-text='{emoji.native}'", don't replace it
if (endsWith(before, 'alt="') || endsWith(before, 'data-text="')) {
return match
}
let emoji = emojiIndex.findEmoji(p2)
if (!emoji) {
return match
}
return before + emojiToHtml(emoji)
})
return text;
}
/**
* Convert Emoji to HTML to represent it as an image.
*/
export function emojiToHtml(emoji: Emoji): string {
let style = `background-position: ${emoji.getPosition()}`
// The src="data:image..." is needed to prevent border around img tags.
return `<img data-text="${emoji.native}" alt="${
emoji.colons
}" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class='emoji-text' style="${style}">`
}
Another solution is to use emoji.native to insert native emoji and then find and replace them with images.
In this case, the application can keep the native emoji in the database and replace with images where needed - in this case, it can do the replacement for browser, but keep unicode emoji for native app.
The good side here is that conflicts are unlikely, we have native unicode emoji as a part of the text and replace them with images for better browser / os support. It means that if browsers improve the color font support in the future, we can just remove the image replacement part and the rest will be working.
The replacement can be done like this (using the emoji-regex package):
// npm install emoji-regex
import emojiRegex from 'emoji-regex'
import data from 'emoji-mart-vue-fast/data/all.json'
import { EmojiIndex } from 'emoji-mart-vue-fast'
const unicodeEmojiRegex = emojiRegex()
export function wrapEmoji(text: string): string {
return text.replace(unicodeEmojiRegex, function(match, offset) {
const before = text.substring(0, offset)
if (endsWith(before, 'alt="') || endsWith(before, 'data-text="')) {
// Emoji inside the replaced <img>
return match
}
// Find emoji object by native emoji.
let emoji = emojiIndex.nativeEmoji(match)
if (!emoji) {
// Can't find unicode emoji in our index
return match
}
// See `emojiToHtml` function above.
return emojiToHtml(emoji)
})
}
Here we can use emojiIndex.nativeEmoji(emoji_char) to get the emoji object by native emoji and then convert it to the HTML image.

Sheets are served from unpkg, a global CDN that serves files published to npm. Note: URLs for background images are specified in the css/emoji-mart.css.
| Set | Size (sheetSize: 16) | Size (sheetSize: 20) | Size (sheetSize: 32) | Size (sheetSize: 64) |
| --------- | ---------------------- | ---------------------- | ---------------------- | ---------------------- |

| twitter | 288 KB | 389 KB | 839 KB | 1.82 MB |
Datasets and Custom Emojis
While the default setup assumes all.json usage with all sets available, you may want to include only a single set data to reduce the size of your bundle.
| Set | Size (on disk) | | --------- | -------------- | | all | 570 KB | | apple | 484 KB | | facebook | 421 KB | | google | 483 KB | | twitter | 484 KB |
To use these data files (or any other custom data), use the Picker component like this:
import data from 'emoji-mart-vue-fast/data/facebook.json'
import { Picker, EmojiIndex } from 'emoji-mart-vue-fast'
let index = new EmojiIndex(data)<picker set="facebook" :data="data" />Using EmojiIndex, it is also possible to control which emojis data is included or excluded via constructor parameters:
| Param | Default | Description |
| ---------------------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| include | [] | Only load included categories. Accepts I18n categories keys. Order will be respected, except for the recent category which will always be the first. |
| exclude | [] | Don't load excluded categories. Accepts I18n categories keys. |
| custom | [] | Custom emojis |
| recent | | Pass your own frequently used emojis as array of string IDs |
| recentLength | | Set the number of emojis for the recent category. |
| emojisToShowFilter | | ((emoji) => true) | A Fn to choose whether an emoji should be displayed or not |
Categories for exclude and include parameters are specified as category id, that are present in data arrays.
Avaiable categories are: people, nature, foods, activity, places, objects, symbols, flags.
For example:
import data from 'emoji-mart-vue-fast/data/facebook.json'
import { Picker, EmojiIndex } from 'emoji-mart-vue-fast'
let emojisToShowFilter = function(emoji) {
// check the emoji properties, see the examples of emoji object below
return true // return true to include or false to exclude
}
let include = ['people', 'nature']
// or exclude:
// let exclude = ['flags']
const custom = [
{
name: 'Octocat',
short_names: ['octocat'],
text: '',
emoticons: [],
keywords: ['github'],
imageUrl: 'https://assets-cdn.github.com/images/icons/emoji/octocat.png?v7',
},
]
let index = new EmojiIndex(data, {
emojisToShowFilter,
include,
exclude,
custom,
})Examples of emoji object:
{
id: 'smiley',
name: 'Smiling Face with Open Mouth',
colons: ':smiley:',
text: ':)',
emoticons: [
'=)',
'=-)'
],
skin: null,
native: '😃'
}
{
id: 'santa',
name: 'Father Christmas',
colons: ':santa::skin-tone-3:',
text: '',
emoticons: [],
skin: 3,
native: '🎅🏼'
}
{
id: 'octocat',
name: 'Octocat',
colons: ':octocat',
text: '',
emoticons: [],
custom: true,
imageUrl: 'https://assets-cdn.github.com/images/icons/emoji/octocat.png?v7'
}Keyboard Controls
When the cursor is in the search field, the Picker component allows to select the emoji with arrow keys.
The selection is confirm with enter, which will emit the selected event (same as when the emoji is clicked with mouse).
Emoji
import data from 'emoji-mart-vue-fast/data/all.json'
import { Emoji, EmojiIndex } from 'emoji-mart-vue-fast'<emoji :data="index" emoji=":santa::skin-tone-3:" :size="32" />

Unsupported emojis fallback
Certain sets don’t support all emojis (i.e. Facebook don’t support :shrug:). By default the Emoji component will not render anything so that the emojis’ don’t take space in the picker when not available. When using the standalone Emoji component, you can however render anything you want by providing the fallback props.
To have the component render :shrug: you would need to:
function emojiFallback(emoji) {
return `:${emoji.short_names[0]}:`
}<emoji set="facebook" emoji="shrug" :size="24" :fallback="emojiFallback" />Headless search
The Picker doesn’t have to be mounted for you to take advantage of the advanced search results.
import { EmojiIndex } from 'emoji-mart-vue-fast'
import data from 'emoji-mart-vue-fast/data/all.json'
const emojiIndex = new EmojiIndex(data)
emojiIndex.search('christmas').map((o) => o.native)
// => [🎄, 🎅🏼, 🔔, 🎁, ⛄️, ❄️]With custom data
import data from 'emoji-mart-vue-fast/data/facebook'
import { EmojiIndex } from 'emoji-mart-vue-fast'
let emojiIndex = new EmojiIndex(data)
emojiIndex.search('christmas')Storage
By default EmojiMart will store user chosen skin and frequently used emojis in localStorage. That can however be overwritten should you want to store these in your own storage.
import { store } from 'emoji-mart-vue-fast'
store.setHandlers({
getter: (key) => {
// Get from your own storage (sync)
},
setter: (key, value) => {
// Persist in your own storage (can be async)
},
})Possible keys are:
| Key | Value | Description |
| ---------- | -------------------------------- | --------------------------------------------------------------------------------------------------------------- |
| skin | 1, 2, 3, 4, 5, 6 | |
| frequently | { 'astonished': 11, '+1': 22 } | An object where the key is the emoji name and the value is the usage count |
| last | 'astonished' | (Optional) Used by frequently to be sure the latest clicked emoji will always appear in the “Recent” category |
Features
Powerful search
Short name, name and keywords
Not only does Emoji Mart return more results than most emoji picker, they’re more accurate and sorted by relevance.

Apple / Google / Twitter / Facebook
Convenience Wrappers
Below are convenience wrappers for Emoji and Picker components that make usage simpler.
These were present before in the project source, but, since they are using all.json for data, that resulted in bigger bundle sizes (as all.json was also included into the any app that is using emoji picker, even if it doesn't need all.json).
So the components were removed and included here as an example.
Picker component wrapper with default settings:
<script>
import data from 'emoji-mart-vue-fast/data/all.json'
import { EmojiIndex } from 'emoji-mart-vue-fast/src/utils/emoji-data'
import EmojiMartPicker from 'emoji-mart-vue-fast/src/components/Picker'
import { PickerProps } from 'emoji-mart-vue-fast/src/utils/shared-props'
let index = new EmojiIndex(data)
export default {
functional: true,
props: {
...PickerProps,
data: {
type: Object,
default() {
return index
},
},
},
render(h, ctx) {
let { data, props, children } = ctx
return h(EmojiMartPicker, { ...data, props }, children)
},
}
</script>Emoji component wrapper with default settings:
<script>
import data from 'emoji-mart-vue-fast/data/all.json'
import { EmojiIndex } from 'emoji-mart-vue-fast/src/utils/emoji-data'
import EmojiMartEmoji from 'emoji-mart-vue-fast/src/components/Emoji'
import { EmojiProps } from 'emoji-mart-vue-fast/src/utils/shared-props'
export default {
functional: true,
props: {
...EmojiProps,
data: {
type: Object,
default() {
let index = new EmojiIndex(data)
return index
},
},
},
render(h, ctx) {
let { data, props, children } = ctx
return h(EmojiMartEmoji, { ...data, props }, children)
},
}
</script>Changelog
Major changes comparing to the original emoji-mart-vue:
- [2021-04-17, v10] Accessibility properties and keyboard controls
- [2021-03-20, v9] Updated to emojis v13, thanks @sgtaziz!
- Updated to emojis v12 (see the breaking change note below)
Performance improvements:
- Reworked emoji index class: use same index (so same data) for all components.
- Render emojis in categories without
Emojicomponent, there are a lot of emojis to render and there is a noticeable slow down when we render a component per emoji. - Frozen objects with emoji data to disable Vue change tracking
- Do not create
EmojiIndexglobally, before it was loaded (along with the emoji data) even when it was not actually used - Extract CSS into external file, use less inline styles to reduce the amount of generated HTML
- Fixes in CSS for native unicode emojis ported from the original react project
- Excluded ./data/all.json from the js bundle (it was always loaded within the bundle even if it is not needed)
- Updated to babel 7
- Added tests
Breaking change in v6: removed Emoji and Picker wrappers, renamed NimbleEmoji to Emoji and NimblePicker to Picker.
See the Convenience Wrappers section below for details.
Breaking change in v7: switched to Unicode v12 emoji set which results in several breaking changes:
- Removed 'emojione' set (removed from emoji-datasource by JoyPixels request)
- Removed 'messenger' set - it was merged into 'facebook' set
- Changed emoji categories: removed 'Smileys & People', added 'Smileys & Emotions' and 'People & Body' instead
Breaking change in v8:
- The
StaticPickercomponent is now default (exported asPicker), previous default component renamed toVirtualScrollPicker
